ABSTRACT:
An adjustable keeper for pin latches, particularly suited for doors or panels mounted in flush relation to the external surface of an aircraft and thus subject to extreme air loads incidental to flying; one or more of the adjustable keepers being positioned for engagement by a corresponding pin latch, and including a screw assembly for adjusting the position of the keeper, the screw assembly having a tool engagable head exposed through a small perforation in the door or panel or adjacent thereto and thus accessible, when the door or panel is closed, to adjust the keeper so as to apply a preselected force to the pin latch which is transmitted to the door or panel to retain the door or panel in its flush condition.
